Non-native species have been introduced at escalating rates during the last decades, mainly due to the dispersion generated by the increasing trade and transport worldwide. Mollusks, the second largest metazoan phylum in terms of species richness, are no exception to this pattern, but, to date, a comprehensive synthesis of non-native mollusk species (NNMS) in South America was not available. For this purpose, an e-discussion group was formed with malacologists and taxonomists from South America, where we exchanged and analyzed bibliography, databases and information about NNMS, providing expert opinion to this assessment. The first list of non-native mollusk species for South America, considering terrestrial, freshwater and marine environments, includes 86 NNMS distributed in 152 ecoregions (terrestrial, freshwater and marine) of the 189 recognized for the South American continent. Information on their native region, vectors, first record for South America and distribution, are also provided. In the analysis of the distribution of the NNMS and the entry points of each species (e.g., ports, cargo and passenger airports, cities) and status of conservation of the ecoregions, four hot spots were recognized: Subtropical-Atlantic,
Contando con la invaluable asistencia participativa y apoyo de investigadores locales, naturalistas y colaboradores informantes de campo, el Projeto AM viene desarrollando investigaciones taxonómicas, bioecológicas y de conservación acerca de los “moluscos exóticos no marinos” presentes en el territorio insular caribeño de la isla La Española (Hispaniola), con especial énfasis en las especies no nativas introducidas (de manera proposital o accidental) en su medio ambiente, siendo inventariadas hasta el momento un total general de 36 especies terrestres y de agua dulce (34 gastrópodos & 2 bivalvos), incluídas en 31 géneros y 21 familias.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
